DP’s son moving in

I suspect I’m being unreasonable here but I thought it would be helpful to get other people’s opinions.

My DP has a DS19, sees him usually once a week when he comes to stay.

We’re due to exchange on a house next week and last night DP dropped in to conversation over dinner that his DS will be moving in full time when we are in the new house.

Now I know this is his son, and I like him, but AIBU to think there should have been slightly more discussion on this? I worry about what else he will drop on me without notice or discussion further down the line. Maybe it’s me being dramatic, it’s just made me feel a little uneasy for some reason.

Hopefully shes had / still having discussions with him and they are sorting it out one way or another. Then maybe we will be updated of outcome.

I would not allow someone to move in if they use drugs. If they got caught with something illegal I would have inform my employer and could lose my job. You do not want your home address linked to illegal activity.

He’s messy and she’s had enough apparently.

And who will nag him to clear up in your house when he’s messy? Absolutely no way would I go ahead with exchanging! Your dp cannot simply dictate this to you. What is the bedroom situation?

She's going to let the son move in.

I think so too. She'll agree not to pull out if certain rules are followed by DPs son.
That went so well in his own mother's house.

Hope it works out for Op. Start as you mean to go on with son, set the ground rules from the off.

Good. Hes his son and should be able to live with his dad if he wants to.

Without any prior discussion? Madness.
He's a 19 year old adult working full time, his mother has had enough of his behaviour, so he should find himself a flat share and not expect his father's partner to take him (and his g/friend and weed) in on his say-so.

He should indeed be able to live with his dad if he wants to, but his dad should discuss this with the other members of the household and not just drop it in their laps as a fait accompli.

OP, so exchanging on Monday?? and burying your money and whole future welfare into it??

Imagine a future in your fifties and onwards with a man who would pull this sort of trick, make you doubt your own reaction, and leave you feeling guilty for being shocked and upset and uneasy, and no doubt has trowelled on the guilt-trip when she later raised - if she raised - any concerns, even just for the manner of the decision being delivered to her as a done deal without any input from her.

@thankfulnessisnotbizarre would you expect them to buy a separate house for your adult DC too?

Noooo, I am joking. I don't have luck with boss guys...I got one humble decent intellectual and will be until death do us part. But if a new one appears, yes, he has got to be a boss and pay up :D

Sometimes the universe gives us a sign. Right now the universe has shown you the man you planned to spend the rest of your life with is a complete ass. Yes, parents should prioritise their children but that doesn't mean they impose them on their partner without any discussion. There has been no talk of how this will work as to cooking, laundry and food let alone getting into the subject of their use of utilities or even asking you about your views. You are meant to put up with a young man even his own mother can't stand to live with. Your "partner" has just presented it as a fait accompli. He just assumes you will suck it all up without complaint. Right now I would not be buying a house with this man. Well to be honest, I would probably never buy a house with this sort of man.

i will never buy a house with a man who has an ex and children from another woman. If they are such a big boss, let them buy a house for me and a separate to their own adult children.

Ok, so many thread where no reply after the majour crux served.

@maximusss I would never put my DP in a position where he has to ‘hurt’ his son’s feelings and potentially damage their relationship just to live with me.

It won’t be forever. If you love your DP then let this ‘out-of-the-blue’ situation happen without resentment.

The issue for me is not the situation, it’s the lack of any discussion. What else is he going to drop on you with no discussion.

really. Now is the time o draw a line before yoh are committed by jointly owning a house.

When you're feeling overwhelmed, one more thing can seem too much.

Also true.

It's just frustrating after asking for opinions, she's decided not to return.

I know it happens all the time on here, it's just frustrating when people leave mid topic after receiving opinions and advice about their dilemma.

Anyway, whatever OP decides, I hope it works out well for her.

I imagine she is, a moment to just say thanks for your input everyone, I've read it and have a lot to think about, wouldn't take a lot of time out of her day.

I imagine the OP is dealing with a whole pile of very difficult and very urgent life decisions and is sensibly focussing on doing that rather than coming back to update the thread. She heard a lot of great advice, and can use that however she wants. It’s not been very long in real life since this all happened.

This. We've all pretty much been saying the same thing for hundreds of posts now, and it's a lot for OP to take on - not just this house surprise, but everyone dog-piling onto the DP that she was happy with until now... She must be in some shock.

I'm sure her time will now be better spent getting a clear head and dealing with this IRL rather than coming back to update. If she does update, I hope it's good news; but if she gets in a pickle, I hope she feels able to come back for support.

Good on yer, @maximusss ! 🤗

Damn OP, you're going to let this happen?

OP has ''left the building '' or been hit by a bus!
